Tiffen 72mm advantiX XLE Series Long Exposure Filter
Produce a smooth, softening effect on objects in motion.
Designed to take extreme long exposure photographs in manual setup, the Tiffen advantiX XLE Filter will allow you to blur any movement in your image. The intensity of this effect is achieved through adjustments in manual mode of aperture, shutter and ISO settings. Designed to remove the near IR polluting light waves that the Tiffen "aXent" filter allows through, the advantiX removes these polluting light waves by introducing an active absorbing element. This element adds a slight greenish color cast to the filter, which can be adjusted for, either in your camera's white balance settings or in your post software afterwards.
NOTE: Since not all IR light waves are removed, Tiffen recommends that you use lenses approved for IR photography on APS-C and Micro 4/3 sensor size cameras.
